Why do you use shrink wrap?
1. Shrink wrap performs the key function of protecting products against dust, moisture and dirt. That is very important for all products. Because of the effectiveness of the seal, fully shrink wrapped products also stay in optimum condition for longer than if exposed to the atmosphere.
2. Shrink wrap also holds products' shape well, so products always look their best, which is a critical consideration for consumer products.
How does shrink wrapping machine work?
How a shrink wrapping machine operates depends on the type of shrink wrapping machine involved. Among them, the L type is the most commonly used.

The L type has two sealing bars, which make a backwards L. The shrink film folds along these bars to create a pocket through the crease of the fold for your products to enter. Once your product is placed in that crease, the other three sides of the shrink film need to be sealed. The machine detects when a product is entirely in the machine to know when to wrap your items with shrink film before pushing it further down the production line.
